| Question: | "We have had the soil on our bent putting greens tested and find it is slightly acid. Should we try to sweeten it? We have also tried a special commercial fertilizer on one patch of grass, while we have used compost alone on another; the fertilizer gave very much better results. Should we discontinue using compost?" |

| Answer/Response: | "A slightly acid condition of the soil is desirable, as fine turf grasses thrive in such a soil, while some weeds are discouraged. You have evidently a slightly wrong impression regarding the use of compost. Usually compost contains slightly less than 1 pound of nitrogen, half a pound of phosphoric acid, and 1 pound of potash, per 100 pounds. Putting green turf only occasionally requires more phosphoric acid or potash than the compost supplies. Also if phosphates and potashes are supplied in excess of the turf requirements, clover, chickweed and various other weeds may be encouraged. Putting green grasses, however, require nitrogen in addition to that contained in compost. The best form of nitrogen, other things being equal, is sulphate of ammonia, which also aids in acidifying the soil. Sulphate of ammonia should be used several times during the year in addition to compost. Apply it at the rate of 3 pounds in hot weather, and 5 pounds in cooler weather, per 1,00 square feet. Mix the sulphate in a sufficient quantity of dry soil to insure an even distribution, and follow the application by thoroughly watering the sulphate into the turf. The brand of fertilizer you are using is a comparatively expensive source of nitrogen. It contains 7 ½ per cent available nitrogen, while sulphate of ammonia contains 20 per cent, or nearly three times as much; at the same time the 1 sulphate can usually be obtained at less cost per ton. You would be well advised to try sulphate instead of the fertilizer you now use, making applications whenever the grass seems to lag or need stimulation." |
